BACKGROUND: Low serum Cu and ceruloplasmin (Cp) concentrations in newborns can be the first indication of a severe Cu deficient intake or, alternatively, of genetic diseases affecting Cu metabolism. However, Cu and Cp concentrations can also be influenced by other variables that render their quantitative results difficult to interpret. Therefore, it is necessary to identify these variables and stratify Cu and Cp concentrations according to these altering factors. METHODS: Serum Cu and Cp concentrations for 564 hospitalized newborns (0-12days of life) are stratified according to their age, prematurity (birth weight or gestational age), type of feeding and inflammatory state (assessed by the serum high sensitivity C-reactive protein (hs-CRP) level) to identify potential correlations...

This historical cohort study aimed to assess the relationship between antenatal maternal C-reactive protein (CRP) level and neonatal outcome preterm premature rupture of membranes (PPROM). We reviewed the records of 70 singleton pregnancies with PPROM between 24 and 34 weeks. Maternal CRP levels of neonates with respiratory distress syndrome, neonatal sepsis, grade 3-4 intraventricular haemorrhage and stage 2-3 necrotizing enterocolitis, perinatal mortality were compared with those without these complications...

BACKGROUND: Among pediatric patients, newborns are at highest risk of developing thromboembolism. Neonatal thromboembolic (TE) events may consist of both venous and arterial thromboses and often iatrogenic complications (eg, central catheterization). Treatment guidelines for pediatric patients with TE events most often are extrapolated from the literature regarding adults. Options for the management of neonatal TE events include expectant management; nitroglycerin ointment; thrombolytic therapy or anticoagulant therapy, or a combination of the two; and surgery...

BACKGROUND: The most severe form of rapidly progressing retinopathy of prematurity (ROP) is termed aggressive posterior ROP (APROP). APROP frequently causes severe visual impairment in affected preterm infants despite timely and appropriate laser treatment. OBJECTIVES: We investigated the postnatal characteristics associated with APROP development in a national Swedish cohort. METHODS: This retrospective, 1:1 matched case-control study included all infants that developed APROP in zone 1 (n = 9) between 2008 and 2012...

While developing adaptive immune responses, young infants are especially vulnerable to serious infections, including sepsis, meningitis, and pneumonia. Antimicrobial proteins and peptides (APPs) are key effectors that function as broad-spectrum anti-infectives. This review seeks to summarize the clinically relevant functional qualities of APPs and the increasing clinical trial evidence for their use to combat serious infections in infancy. Levels of APPs are relatively low in early life, especially in infants born preterm or with low birth weight (LBW)...

Curcumin, a natural pigment for yellow color that originates from turmeric, is a diarylheptanoid widely studied for its anti-inflammatory, anti-angiogenic, anti-oxidant and anti-cancer effects on cells. In placental diseases including preeclampsia and preterm birth, curcumin reduces pro-inflammatory cytokines. Even though curcumin is regarded as a novel chemotherapeutic agent with strong apoptotic effects based on phenolic structure, little is known about its functional effects on choriocarcinoma. Therefore, in the present study, we investigated the chemotherapeutic effects of curcumin on choriocarcinoma cells (JAR and JEG3), which are valuable placental models...

Preterm birth remains the most prevalent cause of neonatal morbidity. This study aimed to evaluate the diagnostic value of SDF-1α, resistin, secretory RAGE (sRAGE), and endogenous secretory RAGE (esRAGE) in preterm labor. A total of 211 pregnant women participated in the study. Group A contained 72 women between 22 and 36 weeks of gestation, with premature labor, who finally had preterm birth. Group B contained 66 women in labor between 37 and 41 weeks of gestation. Women in group A had lower SDF-1α and sRAGE levels than those in group B...

OBJECTIVE: Despite decades of research on risk indicators of spontaneous preterm birth (PTB), reliable biomarkers are still not available to screen or diagnose high-risk pregnancies. Several biomarkers in maternal and fetal compartments have been mechanistically linked to PTB, but none of them are reliable predictors of pregnancy outcome. This systematic review was conducted to synthesize the knowledge on PTB biomarkers identified using multiplex analysis. MATERIALS AND METHODS: Three electronic databases (PubMed, EMBASE and Web of Science) were searched for studies in any language reporting the use of multiplex assays for maternal biomarkers associated with PTB published from January 2005 to March 2014...

BACKGROUND: Prematurity and fetal growth restriction are risk factors for pulmonary hypertension (PH) in infants with bronchopulmonary dysplasia (BPD). Neonatal rats develop PH and vascular remodeling when exposed to hyperoxia. We hypothesize that postnatal growth restriction (PNGR) due to under-nutrition increases the severity of PH induced by hyperoxia in neonatal rats. METHODS: Pups were randomized at birth to litters maintained in room air or 75% oxygen (hyperoxia), together with litters of normal milk intake (10 pups) or PNGR (17 pups)...

Antenatal corticosteroid therapy improves both fetal lung mechanism and gas exchange due to accelerated morphologic development of type one and two pneumocytes. This therapy also enhances the production of surfactant binding proteins and fetal lung antioxidant enzymes. In women with threatening preterm delivery, a single course is advocated between 24 and 34 weeks' gestation with either betamethasone (two doses of 12 mg 24 hours apart) or dexamethasone (4-doses of 6 mg at 12-h intervals). Such treatment reduces the rate of respiratory distress syndrome, comorbidity and mortality in neonates in the first 48 hours of life...

INTRODUCTION: Infection accounts for over 40% of preterm premature rupture of the fetal membranes (PPROM), a major cause of preterm birth. Toll-like receptors (TLR) play key roles in pathogen surveillance but their expression and function in amnion mesenchymal cells (AMC) is unclear. The aims of this study were to determine the expression of all TLR isoforms and the effect of macrophage-activating lipoprotein-2 (MALP-2), derived from a common pathogen involved in PPROM, on human AMC. METHODS: AMC were isolated from normal, term amnion from repeat cesarean section...
